Background: Overall, approximately one-third of all adults are overweight, and another one-third are obese. Since obesity is a major risk factor for hypertension, weight loss by changing eating and activity behaviors are important lifestyle changes for prehypertensive women. Purpose: The purpose of this study was to determine the differences in behavioral and biomarkers for healthy eating and physical activity among normal weight [body mass index (BMI) <25], overweight (BMI>25 and >30), and obese (BMI >30) midlife and older rural prehypertensive women. Conceptual Framework: The Health Promotion Model is the framework for the intervention; however, only behavioral and biomarkers of eating and activity are addressed in this presentation. Subjects: 289 prehypertensive (BP 120-139 systolic or 80-89 diastolic) rural women ages 40-69 are enrolled in a clinical trial focused on the lifestyle changes of healthy eating and physical activity to reduce blood pressure. Methods: Women completed a computerized assessment at a rural research office with reliable and valid measures of behavioral markers, the Block Health Habits and History Questionnaire and the 7-Day Activity Recall. Biomarkers (blood pressure, % body fat, VO2maxest) were measured by specially trained research nurses. Results and Conclusions: 110 (38%) women were overweight, and 125 (43%) were obese. Four separate MANOVAS with Bonferroni correction were conducted with separate group differences found for 2 serum lipids (F=7.758, p=<.001), 4 eating behaviors (F=11.727 p=<.001), and for three biomarkers (F=42.33, p=<.001). Groups were significantly different for triglycerides, HDL cholesterol, daily caloric intake per kg/body wt., % calories from fat and saturated fat, daily meat group servings, blood pressure, % body fat, and VO2maxest. No group differences were found for activity behaviors. Normal, overweight and obese women differed from each other for most behaviors and biomarkers. The findings suggest the need to individualize weight loss interventions for prehypertensive women according to BMI category. This finding is similar to a previous study focusing on healthy eating and activity with a general population of rural women 50 -69. Funded by NINR Grant No. 2 RO1 NR04861
